Well, if the window is open it does. I am not trying to be a smartass, all I am saying is to have that open area you have to strengthen the lexan so it does not flex and bend under those G's. Do you know how thick those windows are in the DSR design?

Not thin. They're ballistic rated. Bulletproof. They have to have to some of thickness to have a rating of 'bulletproof'. They're there for driver protection, not aerodynamics. Whatever the thickness, it's more than the 3/16" lexan they used before the canopies. Remember these things protect drivers from things flying into their face at 330mph. It's gonna have to have some sort of structure to it. It can't be that thin to resist damage at 330mph.

“I think the other technical issue is, the windshield glass is very, very thick. Everything else is pretty much like standardized, mandatory. We can’t make anything different because we don’t own it anymore. Aerodine Composites owns it, where everybody orders it. When it comes out, everything is identical from car-to-car. Brittany (Force) is running one also. It’s identical to what’s on my car.”

In this last one, Antron says it 5/8" thick, which would be close to what they use on F16's. They did use a 3 layer system of 1/2" piece of acrylic plastic, a 2nd layer of a different material .005" thick and a 3rd layer of a 3rd material that's .125" thick. I can't find the article I read that in, but I do remember the stated thickness of each layer.
